Peridot, zoisite or emerald: how to tell a green stone and how to wear it in a ring

Peridot, zoisite or emerald: how to tell a green stone and how to wear it in a ring — 1

The green stone in a piece of jewellery might be peridot, emerald, zoisite, tourmaline or something else. From a distance they all look good; the differences show up in hardness, in how the stone reacts to knocks, and in what happens to it after a few years of wear. Here is what is worth knowing about the three names people search for most: peridot, zoisite and emerald.

What "natural stone" means

A natural stone formed in the earth, not in a lab, and it carries what gemmologists call inclusions: threads, tiny fractures, bubbles, colour that is not even. They are not a flaw to hide. In some stones the inclusions are the signature. That is exactly why two stones of the same mineral never look alike, and why two pieces with "the same" green stone are in fact different.

In Huda Mahdi's work, natural stones sit beside pearls inside a frame of silver wire. No piece repeats, and the stone is often what decides the drawing around it.

Hardness: a useful scale, but not everything

The hardness of a stone is measured on the Mohs scale, from 1 to 10. It tells you how hard the stone is to scratch. Typical values: peridot sits around 6.5–7, emerald 7.5–8, and zoisite (the family tanzanite belongs to) 6–7.

On paper emerald wins. In practice it is not that simple, because hardness is not the same as toughness. Emerald usually carries many inclusions, and a knock on a corner can crack it more easily than the number suggests. Peridot, softer, scratches faster from everyday dust but takes a small shock better.

The practical conclusion: a ring worn every day, brushing desks and door handles, calls for a carefully chosen stone and setting. A necklace or pendant, kept away from knocks, forgives much more.

The three, briefly

**Peridot** is olive green, sometimes leaning yellow. It does not need treatment for colour and sits well with silver. It scratches more easily than emerald, so a peridot ring needs a little attention.

**Emerald** is the "deep" green, with inclusions that are simply expected in emerald. It is harder on the scale but more fragile to knocks. Many emeralds are treated with oils to soften the look of fractures, which is why they should not go in an ultrasonic cleaner or near steam.

**Zoisite** is a mineral with several faces: blue-violet tanzanite is zoisite, but there is green zoisite too, often with pink or black patches. It wears well, but does not like sudden temperature changes.

How this connects to the pieces on the site

On the site, green stones are described as they look, not by the name of the mineral: the green stone ring holds a faceted green stone at the centre of a twisted wire frame with four pearls at the corners; the gold ring carries a rectangular green stone set off-centre; the green stone pendant has a stone shot through with pink and black inside a rosette of silver spirals; the hand chain has a mottled green stone at the back of the hand.

Huda knows the exact name of each stone. If you want to know which stone is in a given piece, you can ask her directly on Instagram before you choose.

What to choose, if you have to choose

If you want a ring to wear every day, ask which stone it is, how deep it sits in the setting and how to care for it. If you want something for less hurried days, a pendant like this green stone one or a necklace lets you choose by colour rather than by hardness.

Either way, avoid sudden temperature changes, chlorine cleaners and ultrasonic cleaning until you know which stone you have. For the silver around the stone, see also how to care for silver jewellery.
